Microstructural analysis of a plasmanitrided tool steel by means of metallography and X-ray diffraction

摘要

Nitrideing leads to improved tribological and corrosive properties of iron alloy components. In order to study the effect of plasma nitriding parameters on the structure of compound layer and diffu- sion zone, a systematic variation of process parameters, tempera- ture and process gas atmosphere has been carried out. Metallo- graphic inspection, X-ray diffraction and glow Discharge Optical Spectroscopy analysis (GDOES) were used in this investigation.
